Overview is a lovely short film about the phenomenon known as the Overview Effect (which to me feels akin to Neil deGrasse Tyson's idea of the Cosmic Perspective). I've transcribed my favorite quote:
“One of the astronauts said, "When we originally went to the Moon, our total focus was on the Moon. We weren't thinking about looking back at the Earth. But now that we've done it, that may well have been the most important reason we went."”
Do yourself a favor and set aside 20 minutes to watch this video today.
